Engine with intake air temperature control system

A gas turbine engine system, comprising:

• a gas turbine engine using a vaporized liquefied gas as fuel, the gas turbine engine configured to ingest intake air from an intake port and direct exhaust gases to an exhaust port;
• a heat exchanger configured to transfer heat from a heat transfer fluid to the liquefied gas to create at least a portion of the fuel by vaporizing the liquefied gas;
• and
• an electronic control system programmed to;
• cool the intake air using the heat transfer fluid when a temperature of the intake air is above a threshold temperature;
• and
• heat the intake air using the heat transfer fluid when the temperature of the intake air is below the threshold temperature.

A gas turbine engine system, comprising:

• a gas turbine engine using a vaporized liquefied gas as fuel, the gas turbine engine configured to ingest intake air and release exhaust gases including NOx;
• a heat exchanger configured to transfer heat from a heat transfer fluid to the liquefied gas to create at least a portion of the fuel by vaporizing the liquefied gas;
• a waste heat removal circuit, the waste heat removal circuit including a network of conduits adapted to circulate the heat transfer fluid through one or more heat generating equipment of the gas turbine engine system to transfer heat from the one or more heat generating equipment to the heat transfer fluid;
• and
• an electronic control system programmed to heat and cool the intake air using the heat transfer fluid to adjust a temperature of the intake air toward a threshold temperature.
